I want a layout above recycler view at the bottom of the screen,(like a frame) so that even when that layout is visible I can still scroll recycler view behind it. So I want to align the frame layout at the bottom of the screen and make it visible and invisible as per requirement. Here is my code.
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.protossoft.root.aesencryption.MainActivity">
<ListView
android:layout_width="match_parent"
android:id="@+id/listView"
android:layout_height="match_parent">
</ListView>
<!-- <RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">-->
<FrameLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
tools:layout_editor_absoluteX="0dp"
tools:layout_editor_absoluteY="443dp">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="10dp"
android:gravity="center"
android:orientation="horizontal">
<ImageView
android:id="@+id/deviceNumberImage"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="0.2"
android:src="@android:drawable/btn_default" />
<TextView
android:id="@+id/deviceNumber"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="0.8"
android:text="990000862471854" />
</LinearLayout>
</FrameLayout>
<!-- </RelativeLayout>-->
I don't have too much of idea about constraint layout, but when I am moving the view at the bottom from the editor, it is using property like
tools:layout_editor_absoluteX="0dp"
tools:layout_editor_absoluteY="443dp"
I want to achieve the same with some property like align_parentBottom. But none of the properties is available for use. What do I need to do so that the frame layout is visible at the bottom and on the top of recycler view at the same time? Thanks :)

You should use app:layout_constraintBottom_toBottomOf="parent"
attribute.
Here's the setup that you need:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
<FrameLayout
android:layout_width="0dp"
android:layout_height="wrap_content"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent">
...
</FrameLayout>
</android.support.constraint.ConstraintLayout>
